The control of magnetism by acoustically induced strain has driven significant research
activities, with the ultimate goal of pursuing novel, ultrafast, compact, and energy-efficient …

In two-dimensional honeycomb ferromagnets, bosonic magnon quasiparticles (spin waves)
may either behave as massless Dirac fermions or form topologically protected edge states …

How a certain ground state of complex physical systems emerges, especially in two-
dimensional materials, is a fundamental question in condensed-matter physics. A …

Magnon polarons are novel elementary excitations possessing hybrid magnonic and
phononic signatures, and are responsible for many exotic spintronic and magnonic …

Polaritons are widely investigated quasiparticles with fundamental and technological
significance due to their unique properties. They have been studied most extensively in …

Spin and lattice are two fundamental degrees of freedom in a solid, and their fluctuations
about the equilibrium values in a magnetic ordered crystalline lattice form quasiparticles …

Magnon polarons, a type of hybridized excitations between magnons and phonons, were
first reported in yttrium iron garnet as anomalies in the spin Seebeck effect responses. Here …

The magnetic insulator yttrium iron garnet (YIG) with a ferrimagnetic transition temperature
of∼ 560 K has been widely used in microwave and spintronic devices. Anomalous features …

We study the topological property of the magnetoelastic excitation in noncollinear
antiferromagnets. As a toy model, we consider the magnon-phonon coupling in a triangular …

The multiferroic materials BiFeO3 and R MnO3 exhibit coexisting magnetic order and
ferroelectricity, and provide exciting platforms for new physics and potentially novel devices …
